If ASP.Net registration is broken:

ASP.NET in IIS: This command installs the ASP.NET version that is associated with the version of the ASP.NET IIS Registration tool that you are using, and updates existing ASP.NET applications. It also switches the DefaultAppPool and the Classic .NET AppPool applications pools to use the .NET Framework 4 CLR. Aspnet_regiis.exe is installed in the Microsoft.NET Framework directory. For .NET Framework 4, the command can be found here:
